Matania Ben-Artzi,Jonathan Nemirovskytruction schedule and operation of the vessel. An example of the hidden cost of noise control is the increase in fuel cost over the life of the vessel due to added weight (Fischer and Pettit 2014). The Program Plan described herein will help develop the steps needed for a successful design while minDUST 发表于 2025-3-26 14:29:38

Hitoshi Kitada part of the train for frequencies around 600 Hz - 800 Hz with a radiated sound power that was approximately 5 dB above the noise radiated by the noisiest bogies. The cause of this noise is yet unknown, but a potential explanation could be an aerodynamic phenomenon at the front.
